vApplication. filed August 27, 1910. Serial No. 579,255.

Massachusetts, have invented an Improve-` -inent in Looms, of which the following description, in connection with the accompa nying drawing, is a specification, like characters on the drawing representing like parts.

This inventionA relatesto looms and particularly to the binder and associated devices for holding the shuttle in the box and preventing rebound thereof.

Looms are commonly provided with a binder, and a binder spring which acts continually on the binder, said binder operating to frictionally engage the shuttle as it 'enters the box and hold it in properposition therein. `Where the binder is 'acting at all times on the shuttle the picker must act with suiiicient force not only to throw the shuttle across the lay, but also to overvcome the friction of the binder against the shuttle as it is leaving the shuttle box and iven to the blow of the picker. to overcome t e frictional resistance of the binder against the shuttle involves the use of considerable power, especially where a large number 'of looms are being run ina single mill.

'It is the object of my invention to provide a novel binder which will uct to apply frictional resistancc'to the shuttle as it enters the box whereby said shuttle will be brought to rest without any rebound. but which will relicvethe shuttle from all frictional pressure while it is being picked. -In Patent No. 962,495, June 2S, '1910, is shown a device of this general nature in which a cam on the crank shaft is employed for relieving the shuttle from the pressure of the binder at the time that the shuttle is to be picked.

In the device lierein'shown, I have done away with binder springs and ein loy a esired the binder pressure to the shuttle when it enters the box and relieving said shuttle from said pressure when it leaves the box.

In the drawings I have shown two embodisimple device which will-secure the -ments of my invention, one involving the use of a front binder, and the other involvingvthe use "oa rear binder.

igure .1 is a fragmentary yiew of a loop;

lwith thelay and shuttle box in section showing my invention applied to a loom havin a binder on the rear of the shuttle box; Fig.

-2 is a similar vicw showing one way of applying my invention to a loom yhaving a binder on the front of the shuttle box; Fig. 3 is amodiication of the device'shown 1n Fig. 1f

In the drawings 3 designates part-of a loom frame, 4 the lay, 5 the shuttle box, k6 the shuttle therein, 7 the binder, 8 the lay swords, and 9 the -connecting rod leading tothe crank. .These vparts are or may be of any suitable construction and form no part ol the )resent-invention.

The inder v7 which is usually pivoted at one end and is adapted to swing inwardly,

is acted on by a finger 10, the movement of which is controlled by a cam 11 carried by the frame of the loom, the construction rbeings-uch that as the lay beats up, the finger 10 in swung forwardly to cause the binder f? to enga e the shuttle, while when the lay 1s on its ack center the arm 10 is allowed to swing away .from the binder to relieve the pressure thereon. There are various ways in which this motion may be given to the finger 10 from the cam 11, and in the embodiment shown in Fig. 1 saidfinger 10 is mounted on an arm 12 which is pivoted to the lay or the lay-sword at 13, so that it may swing upwardly and downwardly.

The finger 10 is shown as having ay roll 14:

of the cam, vwhile when the lay is on the front center, the roll 14 will engage the high portion of the cam. be of any suitable construction and may fbe secured 1n place in any appro riate way. I have herein shown it as provi ed at one end with a stem 17 which is vbolted or otherwise secured to the frame of the loom, as at 18, and if desired the free end of the cam may be supported in a bracket or holder 19. The particular manner of securing the cam to the loom 'frame, however, is not imporv tant.

low portion of the cam just before the shutvtle 1s' picked, Iwhich is usually when 'the This cam 11 may i crank is 'about `on the bottom center. I may provide a similar device for each-shuttle box, or the two arms 12 at each end of thev shuttle boxmay be mounted on a rod which extends the 'length of the lay such,.for instance, as theordinary protector rod so that a cam 11 atlone end of the `loom will suffice. In either event, however, when the lay is in its backward position with the roll 14Qon` the low portion of the cam, there willbe no pressure applied to the binder and the shuttle can be` freely pickedl without having to use 'any more force than is necessary to throwit across thelay. As the lay moves forward and the roll 14 engages the high portion 16 of'the cam, the arm 12 will be swung upwardly, thus causing the linger 10 to actv'on the binder and apply frictional pressure to the shuttle. The change' from the high to the low portion of the camvmay be so timed that when the shuttle is picked it will be relieved from the binder pressure,

` but when it enters the box Aat the other end I `it will be subjected to the binder pressure,

and this pressure will be maintained until the lay moves backwardly again.

I have shown the linger 10 as adjustably mounted on the,arm 12, and as being held in adjusted position by. a clamping screw 20. In Fig. 2 I have shown an arrangement adapted for use with a front binder and in this figure the finger. 10 which acts on t-he binder 7 is `pivoted. to the lay at 21 and is provided with a rearwardly-extending arm 110 constituting a cam member. The upper edge of said cam is shaped ,to present the' low portion 150 and the high portion 16.0. .Secured to the loom frame is a bracket 22 which carries a roll 23 adapted lto engage the up@ edge ofthe cam arm 110. The arrangement of these parts is such that-.when the lay is in its backward position, as seen in Fig. 2, the low portion 150 of the cam engages the roll 23 sol that the binder pressure vis relieved, while as the lay beats forward and the high portion 160 of the cam engages the roll 23, the arm 10 will be turned to cause the binder pressure' to be applied to the shuttle. This cam member is so shaped that the roll 23 fwill pass from the high to.

the low portion and vice versa just asthe `shuttle is picked`v so that the shuttle will be copis of this patent may be obtained for but under some circumstances it may relieved from binder pressure at the time it is picked, but when it enters the box will be subjected to said pressure,4 f

Instead of having the cam. member 11 rigid as in Fig. 1, I may yielding'ly attach it to the loom frame, as shown in Fig.' 3,`in

which caseit is hinged to the loom frame at "Salland is supportedat itsouter endnby a spring 25 sustained in a bracket 26. 'A stop 2 may b'e employed to limit the swinging Vmovement of the cam. If the parts are properly adjusted, the device will work satisfactorily with the cam 11 rigidly sustained,

e desirable to adopta construction in which the cam is yieldingly sustained, and in Fig. 3 I

have shown one way in which this might be` accomplished. l

My invention is not limited to the construction illustrated, as various changes in the parts might be made without departing from the invention. l

Having fully describedl my invention,

what I claim as new and desire to secure by v Letters Patent is In a loom, the combination with a lay hav-` y ing a shuttle box thereon and a binder, of an arm pivotally sustained by the lay and exi. tending backwardly therefrom, a linger ad# justably mounted on said arm and adapted to engage the binder, and a bar'extending ,in the direction of movement of the lay and ,situated so vthat saidiinger continuously engages the upper edge thereof during both lrumr IV.' lloBiNsciN, REMELER C.
